NAME

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include<aio.h>intaio_return(structaiocb*iocb);

DESCRIPTION

The aio_return() system call returns the final status of the asynchronous
I/O request associated with the structure pointed to by iocb.
The aio_return() system call should only be called once, to obtain the
final status of an asynchronous I/O operation once it has completed
(aio_error(2) returns something other than EINPROGRESS).

RETURNVALUES

If the asynchronous I/O request has completed, the status is returned as
described in read(2), write(2), or fsync(2). Otherwise, aio_return()
returns -1 and sets errno to indicate the error condition.

ERRORS

The aio_return() system call will fail if:
[EINVAL] The iocb argument does not reference a completed
asynchronous I/O request.
